Interview with Meryem Mounaj, PhD student in materials chemistry
Currently in the 3ᵉ year of her thesis, Meryem Mounaj, a PhD student at the CERAMATHS laboratory - Université Polytechnique Hauts-de-France, is working on the additive manufacturing of catalytic supports for the conversion of biosourced molecules. In this interview, Meryem shares her academic background, her current research and the motivations that drive her to excel in this promising field.
My background (studies)
Meryem: I completed a scientific baccalaureate, followed by studies in materials chemistry, specializing in inorganic materials chemistry at master's level. Passionate about advanced materials and their environmental applications, I steered my career towards innovative projects combining chemistry and technology to meet ecological challenges. My interest in the practical impact of materials was strengthened by discovering MOFs (Metal-Organic Frameworks)* (cf.illustration 1) and additive manufacturing, which open the way to sustainable solutions.

Conversion example: fructose can be converted into 5-hydroxymethylfurfural (5-HMF), a key molecule for the chemical industry. 5-HMF is a versatile biobased compound used in the production of bioplastics, fuels and other high-value chemicals, offering a sustainable alternative to petroleum derivatives.
My current research
Meryem: I'm working on a project entitled "Additive manufacturing of catalyst supports for the conversion of biosourced molecules". In concrete terms, this involves using stereolithography: an additive manufacturing technique (3D printing) that uses a UV laser to solidify a liquid photopolymerizable resin layer by layer. The aim is to produce complex alumina supports, on which I deposit innovative catalysts such as MOFs (Metal-Organic Frameworks). These supports are then tested for environmentally-friendly chemical reactions, such as the transformation of biomolecules into high-value compounds.
What motivates me in my work
Meryem: what drives me deeply is the opportunity to have a concrete impact on environmental challenges while exploring cutting-edge technologies. I particularly appreciate the connection between scientific innovation and its practical applications. I'm passionate about the experimental and creative nature of my work, and every step forward, however modest, is a source of motivation and satisfaction.
How I see my future
Meryem: I want to move into industrial research on projects in sustainable chemistry, advanced materials or green technologies. My aim is to develop innovations that reduce the environmental footprint of chemical processes. I'm currently working on catalytic supports for the conversion of biosourced molecules, a project geared towards industrial applications. At the same time, I'm strengthening my skills in additive manufacturing and catalysis, while exchanging with experts at international conferences to keep abreast of advances in sustainable chemistry.
My advice to students hesitating to start a doctorate
Meryem: if you're thinking of embarking on a PhD, it's essential to think carefully about your motivations and take the time to choose quality supervision. Supportive and encouraging mentors can make all the difference: they'll support you through the tough times and push you to give your best. If you're passionate about research, curious and ready to take on challenges, a PhD can be an intellectual and personal adventure that's both demanding and deeply rewarding.
